Check Digit Verification of cas no

The CAS Registry Mumber 55544-36-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55544-36:
(7*5)+(6*5)+(5*5)+(4*4)+(3*4)+(2*3)+(1*6)=130
130 % 10 = 0
So 55544-36-0 is a valid CAS Registry Number.

Reactions of Primary and Secondary Amines with Fluoronitrene Generated from Isopropyl N,N-Difluorocarbamate

Klopotek, David L.,Hobrock, Brice G.,Kovacic, Peter,Jones, Martin B.

, p. 1665 - 1667 (2007/10/02)

Isopropyl N,N-difluorocarbamate deaminates primary amines, RNH2, affording RH, N2, RNHCO2-i-C3H7, and RNH2*HF.With secondary amines, dibenzylamine gives bibenzyl, whereas pyrrolidine yields a ring-expansion product, 2,3,4,5-tetrahydropyridazine.The reactions are consistent with the generation of fluoronitrene and subsequent production of the intermediates RN=NH from RNH2 and R2N=N from R2NH.The advantages of using isopropyl N,N-difluorocarbamate as a source of fluoronitrene are discussed.
